Dec 10 (Reuters) - Twitter Inc said it was testing
a feature to show advertisements to people who read tweets
without logging in, as it tries to make good on its long-time
ambition to monetize non-active users.

The company said the feature will help it cash in on an
additional half a billion people each month, pushing its shares
up as much as 7.8 percent to $26.21 on Thursday - their biggest
percentage gain in two months. (bit.ly/1Ok3xiP)

The promoted tweets and videos will be available on
Twitter's desktop website, particularly on people's profile
pages and "tweet detail" pages that highlight specific tweets.

The move will be welcomed by advertisers who have shied away

Facebook Inc, which boasts more than 1.55 billion monthly

Facebook, which had once struggled to monetize its social
networking platform, has been consistently launching tools to
capture ad dollars.
